·Duct type thermal design, reduce the weight of the light and ensure good heat dissipation, lower luminous decay, and also extend life span of the leds.

·Low energy consumption，matching high efficiency constant-current driver, 60% energy saving; with good resistance to over-current, over-voltage, lightning, high temperature, which fully ensure long life span and high stability of the products.

·Durable lights with long life span up to 50000 hours; No need frequent replacements of lights and regular maintenance.
